Hi, I've not been diagnosed with diabetes but it runs in my family. My fasting glucose is usually 97-99 but has been at 123 once and yesterday I checked my glucose less than an hour after a meal and it was at 170. Should I be worried? I've also had a reading of 130 two hours after a carb meal with an energy drink containing sugars. I think it had 25 gram carbs and 24.5 were converted to sugars.
